This is for windows, siding and doors.  They have you fill out a card at concerts, ballgames and at Sam's Club by saying you are being entered into a raffle.  There is no raffle - they are trying to get your number so they can call and bug the heck out of you until you let them come out and give you an estimate.  I wish I would have never filled out that stupid card.  I finally told them that I do not own a home and the calls completely stopped.
